| Why do vaccines provide longer immunity from a virus than natural infection? Posted: 24 Feb 2021 09:38 AM PST I know that the antibodies released by the B cells in the secondary infection will be more specific to the deactivation of the virus for the vaccine compared to natural infection and other advantages like that. However, I couldn't find much when I was looking for the reason that vaccines provide longer immunity, I was only reading how in both cases there will be memory cells for secondary infection. Sources would be greatly appreciated. [link] [comments]  |

| Do we know the climate of Pangaea? Posted: 24 Feb 2021 08:30 PM PST I was wondering if we know the climate of the supercontinent Pangaea, and if we do know then how do we? I tried looking this up but all I got was weather for my town (probably because they both start with p) and the typical description of "Pangaea or Pangea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras." If anyone can answer this question, thank you! [link] [comments]  |
| Is it a legitimate claim to say that random, erratic weather is a result of climate change? Posted: 24 Feb 2021 09:57 PM PST I'm just thinking how over the course of a couple weeks we have swung from very cold temperatures on the East Coast in US and now it feels like spring today. So I guess my question is asking if that sharp change could occur under regular weather patterns or is it so because of climate change. [link] [comments]  |
| Dumb question but, how is Caesium just chilling in the ocean after the Fukushima Daiichi disaster? Posted: 24 Feb 2021 01:01 PM PST I read about how Caesium-134 and 137 were found found in the ocean after the reactor disaster. But I thought Caesium will always react violently with water. So what is going on with that? Did it react with something else and won't switch? Sorry this is probably a dumb question [link] [comments]  |

| What happens when the angular quantum number is greater than 3? Posted: 24 Feb 2021 06:48 PM PST I was learning about quantum numbers, and how the principle quantum number n determines l, the angular momentum quantum number. But when I'm looking at electron configuration for higher elements, it has values of n up 8. This would follow that there are values of l up to 7. The problem is that I'm only taught up to 3 with the f-block. Can someone please explain this? On a related note, what is the purpose of the magnetic quantum number? Does it determine which of the orbitals an electron is in within l? Why are some values of it negative and others positive? Sorry if this is the wrong sub for this question. I just can't find any answers by googling. [link] [comments]  |
| What is the process for decontaminating sites where nuclear waste is present? Posted: 24 Feb 2021 08:29 AM PST Just wondering the main stages after a nuclear event both long term and after and if there is regulations for it Also any links to interesting videos on the subject [link] [comments]  |
| Do nuclear submarines use the hydrogen they get from electrolysis or just dispose of it? Posted: 24 Feb 2021 02:18 PM PST Not 100% sure if this is the right flair, call me out if I'm wrong. I'm curious, since nuclear submarines get their O2 from the water surrounding them do they also use the hydrogen for power or even welding purposes? Or do they have other ways of disposing it? Edit: For some reason I can only see some of the comments... responding is hard when I can't see the comment itself. [link] [comments]  |

| Is Adenovirus "escape" from the lysosome into the cytosol species specific? Posted: 24 Feb 2021 08:24 PM PST I am wondering if human adenovirus was endocytosed/phagocytosed, by an amoeba (for example), would it still be capable of escaping the endosome into the cytosol of the amoeba? I looked into the literature and all I can say is that nothing I read suggested that it isn't a generic process that could work on any endosome... but that is far from a satisfactory answer.

| Posted: 24 Feb 2021 05:08 PM PST Will a shift of the earth's magnetic north pole (from northern Canada to Siberia) affects the polar vortex, if any? Are we going to expect more frequent Artic jet streams pushing southward if so? [link] [comments]  |
| How can light speed up when passing from a dense to a less dense medium? Posted: 24 Feb 2021 10:26 AM PST I took a microscopy course recently and have a question related to Refraction. So, I understand that light slows down when passing into a denser medium. This leads to the light being bend at the border of the two media. (Snell's Law of Refraction) This still makes sense in my head. But apparently it can also "speed up" when passing from a dense to a less dense medium? How is this possible? Where does the energy for acceleration come from? I'm studying molecular biology so I don't understand too much about physics ;) [link] [comments]  |
| If a hose is against more pressure than what it produces, what happens? Posted: 24 Feb 2021 11:20 AM PST For example, if a hose spews water at a certain pressure, and it is facing upwards in a relatively deep water body, which creates more pressure than what the hose is exerting, what happens? Does the water go backwards through the hose? Or does it simply stop? [link] [comments]  |
| Posted: 24 Feb 2021 07:49 AM PST When new strains evolve and spread, this is them evolutionarily out-competing the old strains, right? That is, they're better able to spread their numbers than the old strains are. Isn't this equivalent to saying the new strains are more infectious than the old ones? If so, and this process happens year on year, doesn't that mean the flu virus is evolving to be ever more infectious as time passes? Or am I misunderstand the way new strains work?

| Posted: 24 Feb 2021 02:25 AM PST I ask because humans contain many metals (iron, calcium, etc.) and also we're like 70% water and I've read that water is lowkey magnetic [link] [comments]  |
